Is Blender 2.79 Obsolete now?
Everything in 2.79 is essentially still available in 2.8 and more. Technically 2.8 is still in the open testing phase, but I would recommend learning it now. It doesn't take as long as one may think to figure out where everything is, and I think it's stable enough to replace 2.79. That being said, there's no shame in sticking to 2.79 for now.
